MAUSOLEIHVI-ROOF.

Specification of Letters Patent.

Application filed November 24, 1913. Serial No. 802,680.

To all whom t may concern.'

Be it known that I, CEGIL E. BRYAN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Mausoleum-Roofs, ofwhich the following is a specication.

This invention relates more particularly to roofs which are intended tobe as nearly indestructible and everlasting as possible and, while myimproved form of roof may be arranged with any desired pitch, it isparticularly useful in connection with structures having roofs of slightpitch such as mausoleums as they are' frequently constructed at thepresent time.

There different materials are used for the main structure or support ofthe roof from those used for the outer or covering portion, there is aptto be a difference in the expansion and contraction of the materials,due to the changes in temperature, which is apt to injure the coveringand cause it to crack or loosen.

Among the objects of my invention are to provide a roof in which theexpansion and contraction of the different portions thereof. will notcause any injurious edects; to provide a roof of fire-proofnon-combustible material which will be exceedingly durable and whichwill not be apt to leak; and in general to provide such an improved roofstructure as will be described more fully hereinafter.

In the accompanying drawings illustrating my invention; Figure l is across-sectional view of a portion of a roof embodying the principalfeatures of this invention; Fig. 2 is a plan view of thesame; and Fig. 3is a cross-sectional View showing a slightly modified form ofconstruction.

As indicated in Figs. 1 and 2, the main or supporting portion of theroof comprises a concrete member or slab 4 upon which are placed hollowtile 5, which tile is cemented or secured in position in any desiredmanner. Upon the layer of tile 5i is placed a layer of asbestos paper orother suitable rooing paper 6. A layer 7 of asphalt or other similarmaterial which is both .waterproof and more or less plastic is then laidover the paper 6. The top or upper portion of the roof, which is exposedto thelweather, comprises a layer composed of tiling 8, or othersuitable material, preferably of vitriied character, such as brick orthe like. Thevtile 8 is laid upon the layer of asphalt 7 and the joints9 are filled with hot asphalt or similar binding material which servesto cement and hold the tile or finishing members in position.

It will be readily observed that the layer ofasphalt 7 is fullyprotected from the atmosphere and consequently it will not be subjectedto atmospheric action and will therefore remain in a relatively plasticor yielding condition for a great length of time. The top cover orexposed members being of vitriied or non-yielding material will not beapt to become worn or injured and even if any water passes down betweenthese members it will be carried off by the asphalt layer 7. Theintermediate tile 5 gives an air space between the covering proper andthe main roof portion 4, and as these tile are usually made of clay theywill also serve to prevent rapid changes in the temperature of the mainroofing member. Any variation in the expansion and contraction betweenthe main roong member 4 and the tile or exposed members 8 will belargely compensated for by the plastic layer 7, so that vthe expansionand contraction of the plate or main member 4 will not be apt to injurethe tiling.

In the modified form of construction shown in Fig. 3, the concrete layer4 is dispensed with and large building tiles l0 are used for the mainroof structure, the paper 6 being laid directly upon the building tile.It will also be noted that, in some instances the roofing tile` might bedispensed with and the paper 6 `placed directly upon the concrete' slabor plate 4:. kThe paper forms an exceedingly waterproof material, aslong as it is protected and such layer of paper with the superimposedlayer of asphalt tends to make an absolutelv waterproof roof.

From this description it will be readily seen that I provide a roofstructure which is not apt to be injuriously affected by atmospheriochanges, and one which will be exceedingly durable as well as lendingitself readily to artistic treatment in that the exposed tiling may bechosen with regard to the other materials and when the roof is completedmakes a pleasing appearance.

Having thus described my invention, what I claim and desire to secure byLetters Fatent is:

1. A roof comprising a supporting portion. formed of a layer ofconcrete, hollow tile on s ai supporting portion, alaiyer of Wterprcoffabric on said tile, a layer of asbestos paper' over said portion, alayer of vasphalt substantially one-half inch' thick on said paper, anda layer of floor tiling, on said asphalt, said tiling being held inposition by means of suitable cementing material. f
